Question

我有2张桌子

已注册的事件和事件，但我希望在按下按钮时显示它将事件中的事件移除到已注册的事件中。但我无法删除事件本身我可以隐藏它，以便它显示在网页上的表格中吗？

我正在使用CodeIgniter

！[Cassey领域的Graded Scratch Races事件在两个表格中] [1]

模型

function getAll()
{
// get all the records from the schools table

$this->db->select('*');
$this->db->from('tblMeetRace as met');
$this->db->join('tblLocation as loc', 'loc.intLocationID = met.intLocationID');
$this->db->join('tblEvent as eve', 'eve.intEventID = met.intEventID');
//$this->db->Where('intMemberID = 1' );
$query = $this->db->get();


// if the number of rows returned is more than 0
if( $query->num_rows() > 0) {
    // loop through each record (row) and place that
    // record into an array called $data
    foreach ($query->result() as $row) {
        $data[] = $row;
    }
}
$query->free_result();
// return the array to the controller
return $data;



function getAll1()
{
    // get all the records from the schools table

    $this->db->select('*');
    $this->db->from('tblMeetRace as met');
    $this->db->join('tblLocation as loc', 'loc.intLocationID = met.intLocationID');
    $this->db->join('tblRegistration as reg', 'reg.intMeetRaceID = met.intMeetRaceID');
    $this->db->join('tblEvent as eve', 'eve.intEventID = met.intEventID');
    $this->db->Where('intMemberID = 1' );
    $query = $this->db->get();

    // if the number of rows returned is more than 0
    if( $query->num_rows() > 0) {
        // loop through each record (row) and place that
        // record into an array called $data
        foreach ($query->result() as $row1) {
            $data1[] = $row1;
        }
    }
    $query->free_result();
    // return the array to the controller
    return $data1;
}

控制器

public function getallevents() {
    $this->load->model('events_model');
    $data['records'] = $this->events_model->getAll();
    $data1['records1'] = $this->events_model->getAll1();
    $data3 = $data + $data1;
    $this->load->view('view-events', $data3);
}

尽管你可以更容易地做到这一点，你可以尝试扩展你的第一个查询 - 如果我理解正确的话：

$this->db->select('*');
$this->db->from('tblMeetRace as met');
$this->db->join('tblLocation as loc', 'loc.intLocationID = met.intLocationID');
$this->db->join('tblEvent as eve', 'eve.intEventID = met.intEventID');
$this->db->join('tblRegistration as reg', 'reg.intMeetRaceID = met.intMeetRaceID', 'left');
$this->db->where(array("met.intMeetRaceID" => NULL));

将其添加到不同的表时删除一行
